Simulations of biomass dynamics in community food webs

Abstract: Summary1. Food webs are the backbone upon which biomass flows through ecosystems. Dynamical models of biomass can reveal how the structure of food webs is involved in many key ecosystem properties, such as persistence, stability, etc. 2.

“…Another important factor identified in body size changes on islands are marine subsidies, which increase body size (Lomolino et al, ). Further incorporating marine subsidies through food web models that include biomass dynamics (e.g., Delmas, Brose, Gravel, Stouffer, & Poisot, ) may help to understand and predict the strength of the island rule.…”

“…Describing the change in population density over time is classically done by using ordinary differential equations (ODEs); this approach is applied to model a wide range of ecological systems, from single populations to multitrophic communities (e.g., Delmas, Brose, Gravel, Stouffer, & Poisot, ; Rall et al., ; Rosenzweig & Mac Arthur, ; Verhulst, ). To correctly describe prey depletion during the course of a functional response experiment, we can set up an equation using the generalized Holling functional response (Equation ):dNdt=bN1+q1+bhN1+qP.…”

“…Describing the change of the population density over time is classically done by using ordinary differential equations (ODE); this approach is applied to model a wide range of ecological systems, from single populations up to whole multi-trophic communities (e.g. Verhulst, 1838; Rosenzweig & Mac Arthur, 1963; Rall, Guill & Brose, 2008; Delmas et al , 2016). To correctly describe the prey depletion during the course of a functional response experiment, we can set up such an equation using the generalized Holling functional response (eqn.…”
